# In free-roaming dog populations, does egg-based oral rabies vaccination programmes result in improved bait efficacy?

## TL;DR

This study examines whether egg-based baits improve the effectiveness of oral rabies vaccination in free-roaming dogs compared to meat and fish-based baits.

## Contribution

The study provides weak evidence on bait preference and vaccine efficacy in stray dogs using egg-based oral rabies vaccines.

## Key findings

- Stray dogs may prefer egg-based baits over other types, though evidence is weak.
- Egg-based baits may improve vaccine sachet perforation and vaccination success.
- More research is needed to confirm the effectiveness of egg-based ORVs in stray dog populations.

## Abstract

In free-roaming dog populations, does an egg-based oral rabies vaccination (ORV) compared with meat and fish based ORVs result in improved bait efficacy?

Treatment.

Three non-blinded, control trials were critically reviewed.

Weak.

Variables assessed in this Knowledge Summary included the type of bait that stray dogs were most interested in, and whether or not the dog was successfully vaccinated by release of the vaccine sachet into the oral cavity.

There is weak evidence to show that stray dogs prefer egg-based baits in compared to other bait types, despite egg-based baits allowing for more successful perforation of the vaccine sachet, and hence a higher chance of a successful oral rabies vaccination.
